UNITED STATES GUSTAV HOFMANN, OF BELGRADE, MINNESOTA.

RADIATOR.

Application filed April 23,

To all whom it may concern:

Be it known that I, GUs'rAV HOFMANN, citizen of the United States, residing at Belgrade, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators and has for its principal object to generally improve upon radiators which are used in connection with internal combustion engines for cooling purposes by providing a device which will be of extremely simple, durable and inexpensive construction, one which is eliicient and reliable in operation, and well adapted to the purpose for which it is designed.

Another object of the invention is to provide a partition arranged in a zigzag manner so as to form aplurality of cooling chambers having tubes passing therethrough.

lVith these and numerous other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawing z- Figure 1 is a front elevation of the radiator showing a portion of the forward wall broken away,

Figure 2 is a transverse sectional view taken on the line 22 of Figure 1 looking in the direction of the arrow, and

Figure 3 is a fragmentary enlarged sectional view taken through the radiator showing one of the tubes in section.

Referring to the drawing in detail it will be seen that 1 designates the cooling chamber of the radiator which is formed by the front and rear walls 2 and side walls 8 and is substantially rectangular in transverse cross section as shown in Figure 2. A zigzag partition 4 is arranged in the cooling chamber 1 so as to form the triangularly shaped compartments 5. This zigzag partition 4 eiiiciently braces the casing formed by the walls 1 and 2 so as to present a radiator of comparatively very rigid construction.

1921. Serial No. 463,742.

A plurality of tubes 6 pass through each of the compartments 5 and are arranged so as to pass through the apeXes thereof as is shown to advantage in Figure 2. Each tube 6 is provided with flared ends registering with suitable openings in the front and rear walls 2. The top wall 7 of the cooling chamber 1 is provided with a plurality of apertures so that the various compartments 5 will be in communication with the reservoir 8 to which is delivered the hot water from the internal combustion engine in the usual manner. The compartments 5 will be in communication with each other in the lower portions of the partition 4.

From the foregoing description, taken in connection with the accompanying drawing, the construction and operation of the radiator will be readily understood without a more extended explanation. As numerous changes in form, proportion, and in the minor details of construction may be re sorted to without departing from the spirit of this invention, I do not wish to be limited to the construction herein shown and described other than as claimed.

Having thus described my invention what I claim as new is A radiator comprising a cooling chamber, a reservoir in communication therewith, a zigzag partition arranged in the chamber so as to form a plurality of substantially triangular shaped compartments, said partition provided with apertures in its lower portion so that said compartment-s will be in communication with each other, and a plurality of tubes passing through said com partments and arranged in series so as to pass through the apexes of the compartments, each tube provided with flared end portions.

In testimony whereof I afiix my signatur: in presence of two witnesses:

GUSTAV HOFMANN. Witnesses HENRY WEYDERT, LEVI OETAN.
